We don't know, guys — it totally looks like Rita Ora is super comfortable and used to putting a prick in her butt!!

LOLz! WE HAD TO.

A girl's gotta keep that energy level up, and B12 is the way to do it — and what faster way is there than to just shoot it into your backside?? Rita gets B12 injections straight in the caboose!

What's funny is that not just anyone gives her the injections! Her HAIR STYLIST does it!

Rita does burn the candle at both ends, and the injections are for things like tiredness, lethargy, feeling faint, etc. So she probably fits the bill — especially if she has anaemia! We wonder if they work well for her and that fab body of hers!
